Fully synthetic oils are built from engineered base stocks rather than simply refined from crude, giving them a far more uniform molecular structure. 

In practice, that means better resistance to heat and oxidation, improved flow on cold starts, and a longer useful life, which is why 5W-30 fully synthetic engine oil has become the standard for engines running extended service intervals.

If your handbook specifies the viscosity but you are unsure about the formulation, our full 5W-30 engine oil collection covers every option we carry, including semi-synthetic. Entering your registration in our oil finder is the quickest way to confirm what fits your vehicle.

Buy fully synthetic 5W-30 oil at FIXRA today with free delivery on orders over £20, next-day delivery options, 60-day returns and Click & Collect options for total convenience.
